摘   要：发明了一种新型的拉伸黏结强度试验专用切割装置，对传统的切割方式和拉伸黏结强度试验方法进行了改进。结果表明，新切割装置相对传统切割工具更具效率和精度，切割精度可控在0.5mm。新切割装置和试验方法更具实用性，可对保温装饰板、复合板以及真空绝热板抹面层等复杂系统进行切割试验，效果较好；该装置和方法可应用在保温层与基层、保温层与抹灰层(装饰板) 以及抹灰层与基层的拉伸黏结强度试验中。使用新切割装置能保持切割样品的一致性和均匀性，保温层（或抹灰层）的内部结构不会因为切割而损坏，?覫50mm的粘贴铁块不易出现翘边和不平整等现象，这些优点使得后续的拉伸黏结强度试验结果更为真实可靠。

Abstract: By improving the traditional way of cutting and tensile strength test method, a new type of tensile strength of special cutting device is invented. The results show that the new cutting device is more efficiency and accuracy compared with the traditional cutting tools, and the cutting accuracy can be controlled in the 0.5mm; the new cutting device can be used to take the cut tests of complex systems such as some thermal insulation decoration board, composite board and vacuum insulation panel, and the effect is good; the new cutting device and method can be used in the tensile bond strength tests of insulation layer and the base layer, the insulating layer and the plaster layer (trim) and plastering layer and base layer. Using new cutting device can maintain consistency and uniformity of the cutting sample, the internal structure of thermal insulation layer (layer or plaster) will not be damaged, because cut of ?覫50mm paste such as iron is not easy to become warped edge and uneven phenomenon. Based on the advantages on bonding strength, the follow-up test results is more reliable.
